Santi White is a Philly native, so she and The Roots share that common ground, and they would likely overlap some in their musical geography as well. Like The Roots, Santigold tends to cycle through a vast palette of styles, but she also has keen pop instincts (see "Lights Out") that Black Thought and co. tend to resist. Combine them together and the product would be funky, eclectic, and perhaps radio-ready.
